John Lewins, K92 Chief Executive Officer and Director, stated, “On behalf of the K92 team, we

are very pleased to publish our 2024 Sustainability Report. The report provides our primary

sustainability disclosures for 2024, while highlighting many of our key initiatives that enable us to

deliver sustainable value for all of our stakeholders.

The past year has been truly transformational for K92, as we advance our plans to become a

world-class, Tier 1 gold mining operation. We achieved notable operational successes during the

year in parallel with significant progress on our Stage 3 and Stage 4 Expansions. Importantly, we

have done so with exemplary safety performance, including achieving 553 consecutive days

without a lost -time injury, a testament to the robust health and safety management systems and

practices we continue to implement.

Our local value -retention initiatives continue to deliver significant value for our local

stakeholders. At the end of 2024, we employed nearly 1,800 employees and contractors and

remained a significant tax contributor within the country, with some $62.6M in taxes and royalties

paid in PNG. We also procured approximately $96.5M from PNG companies, including $28.0M

from unique, local Joint Ventures, which are partnerships between established businesses and

local landowner associations that help deliver significant value for local communities.

Looking ahead, the upcoming year will surely be one of the most important in K92’s young history.

During the year, we look forward to the commissioning of our new 1.2 million-tonnes-per-annum

process plant, associated paste plant, and other key mine infrastructure to support our expansion

plans and continued production growth. We also look forward to working in ongoing partnership

with all our stakeholders to deliver transformational value from our operations – now and into the

future.”

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION:

This news release includes certain “forward -looking statements” under applicable Canadian securities

legislation. Such forward -looking statements include, without limitation: (i) the results of the Kainantu

Mine Definitive Feasibility Study, including the Stage 3 Expansion, a new standalone 1.2 mtpa process

plant and supporting infrastructure; (ii) statements regarding the expansion of the mine and development

of any of the deposits; (iii) the Kainantu Stage 4 Expansion, operating two standalone process plants, larger

surface infrastructure and mining throughputs; and (iv) the potential extended life of the Kainantu Mine.

All statements in this news release that address events or developments that we expect to occur in the future

are forward-looking statements. Forward-looking statements are statements that are not historical facts

and are generally, although not always, id entified by words such as “expect”, “plan”, “anticipate”,

“project”, “target”, “potential”, “schedule”, “forecast”, “budget”, “estimate”, “intend” or “believe”

and similar expressions or their negative connotations, or that events or conditions “will”, “wo uld”,

“may”, “could”, “should” or “might” occur. All such forward -looking statements are based on the

opinions and estimates of management as of the date such statements are made. Forward -looking

statements are necessarily based on estimates and assumption s that are inherently subject to known and

unknown risks, uncertainties and other factors, many of which are beyond our ability to control, that may

cause our actual results, level of activity, performance or achievements to be materially different from those

expressed or implied by such forward-looking information. Such factors include, without limitation, Public

Health Crises, including the epidemic or pandemic viruses; changes in the price of gold, silver, copper and

other metals in the world markets; fl uctuations in the price and availability of infrastructure and energy

and other commodities; fluctuations in foreign currency exchange rates; volatility in price of our common

shares; inherent risks associated with the mining industry, including problems r elated to weather and

climate in remote areas in which certain of the Company’s operations are located; failure to achieve

production, cost and other estimates; risks and uncertainties associated with exploration and development;

uncertainties relating to estimates of mineral resources including uncertainty that mineral resources may

never be converted into mineral reserves; the Company’s ability to carry on current and future operations,

including development and exploration activities at the Arakompa, Kor a, Judd and other projects; the

timing, extent, duration and economic viability of such operations, including any mineral resources or

reserves identified thereby; the accuracy and reliability of estimates, projections, forecasts, studies and

assessments; the Company’s ability to meet or achieve estimates, projections and forecasts; the availability

and cost of inputs; the availability and costs of achieving the Stage 3 Expansion or the Stage 4 Expansion;

the ability of the Company to achieve the inputs the price and market for outputs, including gold, silver and

copper; failures of information systems or information security threats; political, economic and other risks

associated with the Company’s foreign operations; geopolitical events and other uncertainties, such as the

conflicts in Ukraine, Israel and Palestine; compliance with various laws and regulatory requirements to

which the Company is subject to, including taxation; the ability to obtain timely financing on reasonable

terms when required; the current and future social, economic and political conditions, including

relationship with the communities in Papua New Guinea and other jurisdictions it operates; other

assumptions and factors generally asso ciated with the mining industry; and the risks, uncertainties and

other factors referred to in the Company’s Annual Information Form under the heading “Risk Factors”.

Estimates of mineral resources are also forward -looking statements because they constitute projections,

based on certain estimates and assumptions, regarding the amount of minerals that may be encountered in

the future and/or the anticipated economics of production. The estimation of mineral resources and mineral

reserves is inherently uncertain and involves subjective judgments about many relevant factors. Mineral

resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any

such estimates is a function of the quantity and quality of available data, and of the assumptions made and

judgments used in engineering and geological interpretation, Forward -looking statements are not a

guarantee of future performance, and a ctual results and future events could materially differ from those

anticipated in such statements. Although we have attempted to identify important factors that could cause

actual results to differ materially from those contained in the forward -looking statements, there may be

other factors that cause actual results to differ materially from those that are anticipated, estimated, or

intended. There can be no assurance that such statements will prove to be accurate, as actual results and

future events could differ materially from those anticipated in such statements. Accordingly, readers should

not place undue reliance on forward -looking statements. The Company disclaims any intention or

obligation to update or revise any forward -looking statements, whether a s a result of new information,

future events or otherwise, except as required by law.
